The Ceres Tournament opened for the Sierra Timberwolves Friday at Riverbank’s Rainbow Fields and Allison Walljasper went to work.

Walljasper was brilliant, twirling a 5-0 perfect game against Enochs and backing it up with another shutout against Merced High.

Sierra (5-0) got a 2-for-4 outing at the top of the lineup from standout Iyana Hughes, as well as a 2-for-3, homerun and double showing from Walljasper, that, to go along with 12 strikeouts and 21-up-21-down pitching.

Her brilliance continued in the second outing, holding a talented Merced club in check for seven innings. Hughes tallied the lone run in the 1-0 nightcap over Merced, stroking a double along with teammate Sommer Wilson.

“The perfect game is great to have but that second game is the one we were really interested in seeing how they responded to a better team,” Sierra head coach Nick Olmo said. “The defense was solid, because you can get a little lackadaisical behind Ally when you’re waiting for something to happen.

“When the ball was put in play they came up and made plays.”

Walljasper would post 12 strikeouts in the win over Merced and Kaitlyn Perkins was 1-for-2 with a walk in the opener.

Sierra will try and pull out the round-robin tournament title when they meet up with Hughson (3:30 p.m.) and Central Catholic (6:30 p.m.) to wrap up tournament play.

Linden Tournament

Ripon 5, Lincoln 4

In a rarity, Ripon hurler Mackenzie Gauden earned a win and a save, re-entering the contest in the sixth inning with the bases loaded to preserve her win in relief of Alyssa Harris Friday in a win over the Trojans.

Gauden struck out 10 on the day, getting a strikeout and a fly out in the final inning.

Nicole Kaiser was 2-for-3 with a double and a RBI, while Melanie Wilkerson was 2-for-3 with a RBI.

Both Taylor Vernon and Kattya Calderon were 1-for-2, with Vernon driving in a run and Calderon hitting a double.

Ripon trailed early behind defensive miscues, but responded after trailing for the first time on the season.

St. Mary’s 8, East Union 7

The Lancers were in cruise control and then all four tires popped.

Leading 7-2 in the sixth inning, East Union could only watch as the Rams turned up with six runs to take an 8-7 lead for good. East Union did exactly nothing to assist the collapse, giving up four hits, four walks and four errors in the forgettable sixth inning.

“We handed it to them, as simple as that,” East Union head coach Brian Goulart said. “The first time we played anybody good and we completely melted down. We didn’t have any nerve and you could tell we played scared. We were up 7-2 and we had them buried.

“Our JV team is undefeated and playing like the varsity team wishes they were.”

Cherish Burks was 2-for-3 with a home run and two runs scored, while both Tea Solario and freshman Michelle Castro were both 2-for-3 with a double. Castro came around to score twice for the Lancers.

Sophomore

East Union 15, St. Mary’s 0

The Lancers blew past St. Mary’s with relative ease, getting a one-hitter from pitcher Lizzy Jordan.

Valerie Ramos was the leading hitter, going 3-for-3 with a homerun and three RBI. Both Amy Gann and Kayce Peterson were both 3-for-3 too.
